In the present discussion the existing data are compared with various model calculations within the ..pi.. NN theory to assess the appropriateness of the latter. Globally the models in their present form reproduce the data quite well in view of the number of channels in which the comparison was made. From the quantitative point of view the models must be upgraded in several different ingredients. First, it is the parameters of the NN heavy meson exchange potentials when combined with the explicit pion and nucleon isobar degrees of freedom. A right choice of their values will lead to a better account of such observables like the beam asymmetries and vector analyzing power in a number of channels like NN in equilibrium ..pi..d, NN ..-->.. ..pi.. NN, etc. The next one may be the model for the ..delta.. resonance (or the ..pi..N P33 off-shell amplitude). A simple monopole or dipole form factor for the ..pi..N..delta.. vertex had difficulty in reproducing the major NN partial wave phase parameters. In view of the fact that dsigma/d..cap omega.. for the deuteron photodisintegration in the ..delta.. resonance region cannot be explained at all by the coupled NN-N..delta.. model, one should seriously consider a better model for the ..delta ... 39 refs., 10 figs.

Progress made in developing a .pi. NN model for describing all NN and .pi.d reactions up to intermediate energy regions is reported. An accurate .pi. NN model is the starting point of developing a microscopic description of nuclear phenomena up to the energy region where pion production can occur. The model can be used to carry out many-nucleon calculations, such as the calculations of pion absorption and electroproduction of .delta. on nuclei. It reduces to existing nuclear theory in the low energy region. 5 refs., 6 figs.

A general .pi. NN theory is discussed which has been constructed according to the present understanding of the quark dynamics. The mechanisms are discussed qualitatively which should be considered in defining the .pi. NN interactions. A model hamiltonian is given. An interpretation is adopted that the confined q6 states are the dibaryon (one-body) states which could be excited at a very short distance during the NN or .pi.d scattering. 11 refs., 7 figs. (LEW).
